Toothpaste, shaving cream, soap, mouthwash and dead skin: These are just a few of the things you are putting into your bathroom sink on a regular basis. Is it any wonder you have a foul odor escaping from the sink? After all, when you are putting all of this debris into the sink, there is a chance that it is coating your pipes and building up over time. There is a term for this; it is called biofilm, and it could be the answer to your question about that strange smell.


Removing Biofilm From Your Trap 

Bathroom cleaning tipsFortunately, thanks to easy-to-perform home remedies, there is no need for a professional. You can get rid of this smell on your own. Before you can get rid of the odor in your sink, you will have to remove some parts. Remove the P-trap, gooseneck, pivot rod and pop-up drain stopper from the sink. There is little doubt you will see these pieces are covered in gunk. It may be a good idea to put a large pot of water on the stove to start boiling, because you are probably going to need it before you are finished. 

You want to remove all the gunk from your sink parts, and there is a method for doing this so that it is effective. Here are the steps to removing the gunk: 

Step 1: Scrape any residue from the drain wall. This can be accomplished by using an iced tea spoon, or you can use a brush that will fit in the drain; a bottle brush or an appliance brush usually works well. 

Step 2: Clean the gunk from the sink drain. To do this, roll up a paper towel and use the same brush you used in the drain to force it into the sink drain. Remember, you have removed the stopper so you have free rein to clean this area well. Repeat this process until you can no longer move debris. 

Step 3: Clean the P-trap and gooseneck. Using the same process you used to clean the gunk from the drain is usually the most effective way to clean these parts. The more contaminants you remove, the less likely it is that you will have lingering odors.

If you prefer to avoid bleach, you can use baking soda or vinegar instead. You should let these parts soak for about 10 minutes. 

Step 5: Put all parts back in place. Replace all of the parts you have removed and make sure they are secure. You should run small amounts of water in the sink to ensure you have tightened everything back up sufficiently to avoid leaks. 

Step 6: Kill the remaining biofilm. The final step in the process is to pour boiling water down the sink drain to kill any remaining biofilm. Pour the water about two cups at a time until you have used about two quarts; this should be sufficient to remove any lingering biofilm. 

Chances are you are not going to stop using your bathroom sink, and that means you will find there is an accumulation of biofilm because of all the debris that winds up down the drain. Fortunately, this home remedy is a simple fix to eliminate that nasty odor created from this type of buildup. In nearly all cases, this process will only take about an hour of your day.
